THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.
.DAY ONE...TODAY AND TONIGHT.
WEATHER HAZARDS EXPECTED:
THUNDERSTORMS...WHICH MAY PRODUCE:
WINDS IN EXCESS OF 60 MPH.
QUARTER SIZE HAIL.
FREQUENT CLOUD TO GROUND LIGHTNING.
TORRENTIAL DOWNPOURS.
AREAS AFFECTED AND TIMING:
THERE IS A SLIGHT CHANCE FOR THE DEVELOPMENT OF A FEW ISOLATED
STORMS THIS AFTERNOON. HOWEVER...THE MAIN FOCUS FOR SEVERE
THUNDERSTORMS WILL SPREAD SOUTHEASTWARD ACROSS NORTHERN
ILLINOIS BY EARLY THIS EVENING AND CONTINUE ACROSS EAST CENTRAL
ILLINOIS AND NORTHWESTERN INDIANA DURING THE LATE EVENING AND
OVERNIGHT HOURS.
DISCUSSION:
A COLD FRONT WILL DROP SOUTHEASTWARD ACROSS SOUTHERN WISCONSIN
LATE THIS AFTERNOON. THE AIRMASS TO THE SOUTH OF THIS FRONT IS
EXPECTED TO BECOME VERY WARM AND MOIST...RESULTING IN UNSTABLE
CONDITIONS ACROSS THE AREA. AS AN UPPER LEVEL DISTURBANCE
APPROACHES THE AREA LATE THIS AFTERNOON AND
EVENING...THUNDERSTORMS WILL DEVELOP ACROSS SOUTHERN WISCONSIN
BY LATE AFTERNOON. THE STORMS MAY THEN FORM INTO SOUTHEASTWARD
MOVING LINES CAPABLE OF PRODUCING STRONG DAMAGING WINDS IN
EXCESS OF 60 MPH ACROSS NORTHERN ILLINOIS INTO THIS EVENING.
ALTHOUGH STRONG WINDS WILL BE THE PRIMARY SEVERE THREAT...THERE
IS ALSO A SECONDARY THREAT FOR QUARTER SIZE HAIL. THESE STORMS
MAY CONTINUE TO BE SEVERE AS THEY MOVE ACROSS EAST CENTRAL
ILLINOIS AND NORTHWESTERN INDIANA LATER IN THE EVENING AND
OVERNIGHT. HOWEVER...THERE IS SOME QUESTION AS TO WHETHER OR
NOT THEY WILL BEGIN WEAKENING PRIOR TO REACHING THESE AREAS.
THEREFORE THE SEVERE THREAT IS MORE UNCERTAIN FOR AREAS TO THE
SOUTHEAST OF THE CHICAGO METRO AREA. TORRENTIAL DOWNPOURS ARE
EXPECTED WITH THESE STORMS...BUT DO TO THE FAIRLY QUICK
MOVEMENT...EXTREME RAINFALL AMOUNTS ARE UNLIKELY.
PORTIONS OF THE ILLINOIS RIVER WILL REMAIN IN FLOOD TODAY.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
THERE WILL BE PERIODIC CHANCES OF THUNDERSTORMS LATE MONDAY NIGHT
THROUGH WEDNESDAY AND AGAIN SATURDAY.
.SPOTTER INFORMATION STATEMENT...
SPOTTERS MAY BE NEEDED ACROSS NORTHERN ILLINOIS THIS EVENING.
